php類庫給現(xiàn)有的圖片加文字水印，代碼不是很完善，歡迎大家多多指教！代碼如下：

  2. /*PHP圖片加文字水印類庫
  4. QQ:3697578482 傷心的歌
  6. 該類庫暫時(shí)只支持文字水印，位置為右下角，顏色隨機(jī)
  8. 調(diào)用方法：
  9. 1、在需要加水印的文件頂部引入類庫：
  10. include_once 'imageClass.php';
  11. 2、聲明新類：
  12. $tpl=new image_fu;
  13. 3、給圖片水印提供參數(shù)：
  14. $tpl->img(圖片路徑,水印文字,字體路徑,字體大小,字體角度);
  15. 比如：$tpl->img('abc.jpg','這是水印文字','ziti.ttf',30,0)
